Swift AVAudioPlayer wont play audio recorded with AVAudioRecorder

Question

I have built an app that records an audio clip, and saves it to a file called xxx.m4a.

Once the recording is made, I can find this xxx.m4a

Answer 1

In the place where you want to use the Playback using speakers before you initialize your AVAudioPlayer, add the following code:

let recordingSession = AVAudioSession.sharedInstance()
        do{
            try recordingSession.setCategory(AVAudioSessionCategoryPlayback)
        }catch{

        }

and when you are just recording using AVAudioRecorder use this before initializing that:

do {
            recordingSession = AVAudioSession.sharedInstance()
            try recordingSession.setCategory(AVAudioSessionCategoryRecord)
    }catch {}

Answer 2

You playing code is fine; your only problem is with the scope of your AVAudioPlayer object. Basically, you need to keep a strong reference to the player around all the time it's playing, otherwise it'll be destroyed by ARC, as it'll think you don't need it any more.

Normally you'd make the AVAudioPlayer object a property of whatever class your code is in, rather than making it a local variable in a method.
